18.3 Energy saving and optimum operation
This heat pump system is equipped with advanced energy saving functionality.
Depending on the priority, emphasises can be put on energy saving or comfort
level. Several parameters can be selected, resulting in the optimal balance
between energy consumption and comfort for the particular application.
Several patterns are available and explained below. Modify the parameters to the
needs of your building and to realize the best balance between energy
consumption and comfort.
No matter which control is selected, variations on the behaviour of the system are
still possible due to protection controls to keep the unit operating under reliable
conditions. The intentional target, however, is fixed and will be used to obtain the
best balance between energy consumption and comfort, depending on the
application type.
